Minimum RISC-V: Maximum FPGA Efficiency
Martin Langhammer, Bogdan Pasca, Gregg Baeckler
RISC-V processors are now widely available for FPGAs, with most FPGA vendors replacing their proprietary soft-CPU architectures with this instruction-set architecture (ISA). Althou…
A 950 MHz SIMT Soft Processor
Martin Langhammer, Gregg Baeckler, Kim Bozman
Although modern FPGAs have a performance potential of a 1 GHz clock frequency - with both clock networks and embedded blocks such as memories and DSP Blocks capable of these clock…
Banked Memories for Soft SIMT Processors
Martin Langhammer, George A. Constantinides
Recent advances in soft GPGPU architectures have shown that a small (<10K LUT), high performance (770 MHz) processor is possible in modern FPGAs. In this paper we architect and eva…
Soft GPGPU versus IP cores: Quantifying and Reducing the Performance Gap
Martin Langhammer, George A. Constantinides
eGPU, a recently-reported soft GPGPU for FPGAs, has demonstrated very high clock frequencies (more than 750 MHz) and small footprint. This means that for the first time, commercial…
A Statically and Dynamically Scalable Soft GPGPU
Martin Langhammer, George A. Constantinides
Current soft processor architectures for FPGAs do not utilize the potential of the massive parallelism available. FPGAs now support many thousands of embedded floating point operat…
